      • OrdType(4) supports new value P(PEGGED)
      • Tags PegOffsetValue(211), PegPriceType(1094), PegMoveType(835), and PegOffsetType(836) have been added to the following messages:
        • NewOrderSingle <D>
        • NewOrderList <E>
        • OrderCancelRequestAndNewOrderSingle <XCN>
        • When placing an order, the ExecutionReport <8> message will echo back PegInstructions, with an extra optional field PeggedPrice (839).
    • New error messages for pegged orders are added. Please see the Errors document for more information.
  • Changes with recvWindow:
    • A third check is made after your message leaves the message broker just before it is sent to the Matching Engine.
      • This does not cover potential delays inside the Matching Engine itself.
    • recvWindow supports microseconds.
      • The value is still specified in milliseconds, but can now take a decimal component to specify it with higher precision.
      • This means that the parameter supports a maximum precision of 3 decimal places. (e.g. 6000.346)
      • APIs affected:
        • FIX API
        • REST API
        • WebSocket API
  • The following requests have a new structure called specialCommission. See Commission Rates.

      • POST /api/v3/sor/order/test with computeCommissionRates=true
    • WebSocket API
      • account.commission
      • order.test with computeCommissionRates=true
      • sor.order.test with computeCommissionRates=true
  • The new MAX_NUM_ORDER_AMENDS filter is enabled with a limit of 10 amendments per order.
  • New error codes -1120 and 1211. See Errors for more information.
  • SBE: A new schema 3:1 (spot_3_1.xml) is available.
    • The current schema 3:0 (spot_3_0.xml) is deprecated and will be retired in 6 months as per our schema deprecation policy.
    • Changes in schema 3:1:
      • ExchangeInfoResponse: new field pegInstructionsAllowed
      • ExecutionReportEvent: new fields pricePeg, pricePegOffsetLevel, peggedPrice
      • UserDataStreamSubscribeResponse: new field subscriptionId
      • New field subscriptionId for all user data stream events.

      • Support for EXCHANGE_MAX_NUM_ORDER_LISTS, MAX_NUM_ORDER_LISTS, and MAX_NUM_ORDER_AMENDS filters.
      • ExecutionReportEvent: fields rejectReason and origClientOrderId now show their default values in SBE format to match the JSON format.
      • NonRepresentableMessage: New message added to represent a message that cannot be represented in this schema ID and version. Receipt of this message indicates that something should be available, but it is not representable using the SBE schema currently in use.
  • Query order lists requests will first query the data in the cache, and if it cannot be found will query the database.
    • REST API: GET /api/v3/openOrderLists
    • WebSocket API: openOrderLists.status
  • Orders with cumulative quantity of 0 in the final state EXPIRED_IN_MATCH (i.e. the order expired due to STP) will be archived after 90 days.
  • Bug fix: The Matching Engine no longer accepts order lists that exceed the order count filter limits. Affected filters:
    • MAX_NUM_ORDERS
    • MAX_ALGO_ORDERS
    • MAX_ICEBERG_ORDERS
    • EXCHANGE_MAX_NUM_ORDERS
    • EXCHANGE_MAX_ALGO_ORDERS
    • EXCHANGE_MAX_ICEBERG_ORDERS

WebSocket API​

  • A single WebSocket connection can subscribe to multiple User Data Streams at once.
    • Only one subscription per account is allowed on a single connection.
  • Method userDataStream.subscribe.signature has been added that allows you to subscribe to the User Data Stream without needing to login first.
    • This also doesn’t require an Ed25519 API Key, and can work with any API Key type.
    • For SBE support you need to use schema 3:1 at least.
  • Method session.subscriptions has been added that lists all the subscriptions active for the current session.
  • The meaning of the field userDataStream in the session requests has changed slightly.
    • Previously, this returned true if you were subscribed to the user data stream of your logged-on account.
    • Now it returns true if you have at least one active user data stream subscription
      • true - If there is at least one subscription active
      • false - If there are no active subscriptions
  • userDataStream.unsubscribe supports closing multiple subscriptions.
    • When called with no parameter, this will close all subscriptions.
    • When called with subscriptionId, this will attempt to close the subscription matching that Id, if it exists.
    • The authorization for this request has been changed to NONE.

User Data Stream​

  • Field subscriptionId has been added to the User Data Stream events payload when listening through the WebSocket API. This will identify which subscription the event is coming from.

FIX API​

  • When a client sends a reject message, the FIX API will no longer send the client back a Reject <3> message. Error messages are clearer when a tag is invalid, missing a value, or when the field value is empty or malformed
    • If the tag number was invalid, you will receive the error: 
      { "code": -1169, "msg": "Invalid tag number." }
    • If a valid tag was specified without a value, you will receive the error: 
      { "code": -1177, "msg": "Tag specified without a value." }
    • If the field value was empty or malformed, you will still receive the error: 
      { "code": -1102, "msg": "Field value was empty or malformed." }

REST and WebSocket API:

2025-05-21​

Notice: The following changes will happen at 2025-05-21 7:00 UTC.

  • The previous behavior of recvWindow on FIX, REST, and WebSocket APIs will be augmented by an additional check.
    • To review, the existing behavior is:
      • If timestamp is greater than serverTime + 1 second at receipt of the request, the request is rejected. Rejection by this check increments message limits (FIX API) and IP limits (REST and WebSocket APIs), but not Unfilled Order Count (order placement endpoints of all APIs).
      • If the difference between timestamp and serverTime at receipt of the request is greater than recvWindow, the request is rejected. Rejection by this check increments message limits (FIX API) and IP limits (REST and WebSocket APIs) but not Unfilled Order Count (order placement endpoints of all APIs).
    • The additional check is:
      • Just before a request is forwarded to the Matching Engine, if the difference between timestamp and the current serverTime is greater than recvWindow, the request is rejected. Rejection by this check increments message limits (FIX API), IP limits (REST and WebSocket APIs), and Unfilled Order Count (order placement endpoints of all APIs).
    • The documentation for Timing security has been updated to reflect the additional check.
  • Fixed a bug in FIX Market Data message InstrumentList <y>. Previously, the value of NoRelatedSym(146) could have been incorrect.

2025-04-29​

  • Features that currently require an Ed25519 API key will soon be opened up to HMAC and RSA keys.
    • For example, subscribing to User Data Stream in WebSocket API will be possible with any API key type before listenKeys are removed.
    • Users are still encouraged to migrate to Ed25519 API keys as they are more secure and performant on Binance Spot Trading.
    • More details to come.

2025-04-25​

  • Notice: The following changes will happen at 2025-04-25 09:00 UTC.
  • The following request weights will be increased from 1 to 4:
    • REST API: PUT /api/v3/order/amend/keepPriority
    • WebSocket API: order.amend.keepPriority
    • The documentation for both REST and WebSocket API has been updated to reflect the upcoming changes.
  • Clarified that SEQNUM in the FIX-API is a 32-bit unsigned integer that rolls over. This has been the SEQNUM data type since the inception of the FIX-API.

2025-04-21​

2025-04-01​

Notice: The following changes will be deployed tomorrow April 2, 2025 starting at 7:00 UTC and may take several hours to complete.
Please consult the Spot Test Network's homepage to be informed of the release completion.

New Features​

  • Order Amend Keep Priority is now available.
    • FIX API: New Order Entry Messages OrderAmendKeepPriorityRequest and OrderAmendReject
    • REST API: PUT /api/v3/order/amend/keepPriority
    • WebSocket API: order.amend.keepPriority
    • You can check the new allowAmend field in Exchange Information Requests to see if it's enabled on a given symbol:
      • REST API: GET /api/v3/exchangeInfo
      • WebSocket API: exchangeInfo
  • Self-trade prevention mode DECREMENT is now available.
    • Instead of expiring one or both orders, DECREMENT mode decreases the available quantity of both orders by increasing the prevented quantity of both orders by the amount of the prevented match.
    • This can expire the orders if their filled quantity + prevented quantity >= order quantity.
    • You can check the allowedSelfTradePreventionModes field in Exchange Information Requests to see if this mode is enabled on a given symbol.

General Changes​

  • Important: The following legacy URLs will be removed in May 2025. Please change to the new URLs as soon as possible:
Legacy URLLatest URL

  • Behavior when querying and/or canceling with orderId and origClientOrderId/cancelOrigClientOrderId:
    • The behavior when both parameters were provided was not consistent across all endpoints.
    • Moving forward, when both parameters are provided, the order is first searched for using its orderId, and if found, origClientOrderId/cancelOrigClientOrderId is checked against that order. If both conditions pass, the request succeeds. If both conditions are not met the request is rejected.
    • Affected requests:
      • REST API:
        • GET /api/v3/order
        • DELETE /api/v3/order
        • POST /api/v3/order/cancelReplace
      • WebSocket API:
        • order.status
        • order.cancel
        • order.cancelReplace
      • FIX API
        • OrderCancelRequest <F>
        • OrderCancelRequestAndNewOrderSingle <XCN>
  • Behavior when canceling with listOrderId and listClientOrderId:
    • The behavior when both parameters were provided was not consistent across all endpoints.
    • Moving forward, when both parameters are passed, the order list is first searched for using its listOrderId, and if found, listClientOrderId is checked against that order list. If both conditions are not met the request is rejected.
    • Affected requests:
      • REST API
        • DELETE /api/v3/orderList
      • WebSocket API
        • orderList.cancel
  • Previously, the request weight for myTrades was 20 regardless of the parameters provided. Now, if you provide orderId, the request weight is 5.
    • REST API: GET /api/v3/myTrades
    • WebSocket API: myTrades
  • If the unfilled order count for intervalNum:DAY is exceeded, the unfilled order count for intervalNum:SECOND is no longer incremented.
  • Change when querying and deleting orders:
    • When neither orderId nor origClientOrderId are present, the request is now rejected with -1102 instead of -1128.
    • Affected requests:
      • REST API:
        • GET /api/v3/order
        • DELETE /api/v3/order
      • WebSocket API
        • order.status
        • order.cancel
      • FIX API
        • OrderCancelRequest <F>
  • New Error code -2038 for order amend keep priority requests that fail.
  • New messages for error code -1034.

FIX API​

  • The QuickFix schema for FIX OE is updated to support the Order Amend Keep Priority feature and new STP mode, DECREMENT.
  • FIX Order Entry connection limits will be a maximum of 10 concurrent connections per account.
  • The connection rate limits are now enforced. Note that these limits are checked independently for both the account and the IP address.
    • FIX Order Entry: 15 connection attempts within 30 seconds
    • FIX Drop Copy: 15 connection attempts within 30 seconds
    • FIX Market Data: 300 connection attempts within 300 seconds
  • News <B> contains a countdown until disconnection in the Headline field.
    • Following the completion of this update, when the server enters maintenance, a News message will be sent to clients every 10 seconds for 10 minutes. After this period, clients will be logged out and their sessions will be closed.
  • OrderCancelRequest <F> and OrderCancelRequestAndNewOrderSingle <XCN> will now allow both orderId and clientOrderId.
  • FIX API verifies that EncryptMethod(98) is 0 at Logon <A>.

User Data Streams​

  • Receiving user data streams on stream.testnet.binance.vision using a listenKey is now deprecated.
    • This feature will be removed from our systems at a later date.
  • Instead, you should get user data updates by subscribing to the User Data Stream on the WebSocket API.
    • This should offer slightly better performance (lower latency).
    • This requires the use of an Ed25519 API Key.
  • In a future update, information about the base WebSocket endpoint for the User Data Streams will be removed.
  • In a future update, the following requests will be removed from the documentation:
    • POST /api/v3/userDataStream
    • PUT /api/v3/userDataStream
    • DELETE /api/v3/userDataStream
    • userDataStream.start
    • userDataStream.ping
    • userDataStream.stop
  • The User Data Stream documentation will remain as reference for the payloads you can receive.

SBE​

  • A new schema 3:0 (spot_3_0.xml) is now available.
    • The current schema 2:1 (spot_2_1.xml) is now deprecated and will be retired in 6 months as per our schema deprecation policy.
    • Note that trying to use schema 3:0 before it is released will result in an error.
  • Changes in schema 3:0:
    • Support for Order Amend Keep Priority:
      • Added field amendAllowed to ExchangeInfoResponse.
      • New Messages OrderAmendmentsResponse and OrderAmendKeepPriorityResponse
    • Breaking changes:
      • All enums now have a NON_REPRESENTABLE variant. This will be used to encode new enum values in the future, which would be incompatible with 3:0.
      • New enum variant DECREMENT for selfTradePreventionMode and allowedSelfTradePreventionModes
      • symbolStatus enum values AUCTION_MATCH, PRE_TRADING and POST_TRADING have been removed.
      • Fields usedSor, orderCapacity, workingFloor, preventedQuantity, and matchType are no longer optional.
      • Field orderCreationTime in ExecutionReportEvent is now optional.
  • When using deprecated schema 2:1 on the WebSocket API to listen to the User Data Stream:
    • ListStatusEvent field listStatusType will be rendered as ExecStarted when it should have been Updated. Upgrade to schema 3:0 to get the correct value.
    • ExecutionReportEvent field selfTradePreventionMode will be rendered as None when it should have been Decrement. This only happens when executionType is TradePrevention.
    • ExecutionReportEvent field orderCreationTime will be rendered as -1 when it has no value.
  • All schemas below 3:0 are unable to represent responses for Order Amend Keep Priority requests and any response that could contain the STP mode DECREMENT (e.g. Exchange Information, order placement, order cancelation, or querying the status of your order). When a response cannot be represented in the requested schema, an error is returned.

2025-03-31​

  • Added a clarification on the performance of canceling an order.

2025-03-13​

  • Notice: The following changes will happen on March 13,2025 at 05:00 UTC:

    The following request weights will be increased from 2 to 4:
    • REST API: GET /api/v3/aggTrade
    • WebSocket API: trades.aggregate
  • The documentation for both REST and WebSocket API has been updated to reflect the upcoming changes.

2025-02-28​

  • SBE Market Data Streams are now available. These streams offer a smaller payload and should offer better latency than the equivalent JSON streams for a subset of latency-sensitive market data streams.
  • Streams available in SBE format:
    • Real-time: trade stream
    • Real-time: best bid/ask
    • Every 100 ms: diff. depth
    • Every 100 ms: partial book depth
  • For more information please refer to the SBE Market Data Streams.

2025-02-05​

  • Notice: These changes will be deployed starting at 7:00 UTC, and may take several hours to complete. The following changes will apply to WebSocket Market Data Streams, User Data Streams, and the WebSocket API:

Note: These changes will be deployed live starting 2024-11-28 and may take several hours for all features to work as intended.

New Feature: Microsecond support:

The system now supports microseconds in all related time and/or timestamp fields. Microsecond support is opt-in, by default the requests and responses still use milliseconds.

Examples in documentation are also using milliseconds for the foreseeable future.

WebSocket Streams

  • A new optional parameter timeUnit can be used in the connection URL to select the time unit.
    • For example: /stream?streams=btcusdt@trade&timeUnit=millisecond
    • Supported values are:
      • MILLISECOND
      • millisecond
      • MICROSECOND
      • microsecond
    • If the time unit is not selected, milliseconds will be used by default.

REST API

  • A new optional header X-MBX-TIME-UNIT can be sent in the request to select the time unit.
    • Supported values:
      • MILLISECOND
      • millisecond
      • MICROSECOND
      • microsecond
    • The time unit affects time-related parameters in requests (e.g, startTime, endTime, timestamp).
    • The time unit affects timestamp fields in responses (e.g., time, transactTime).
    • If the time unit is not selected, milliseconds will be used by default.

WebSocket API

  • A new optional parameter timeUnit can be used in the connection URL to select the time unit.

General Changes:

  • Fixed a bug that prevented orders from being placed when submitting OCOs on the BUY side without providing a stopPrice.

  • TAKE_PROFIT and TAKE_PROFIT_LIMIT support has been added for OCOs.

    • Previously OCOs could only be composed by the following order types:
      • LIMIT_MAKER + STOP_LOSS
      • LIMIT_MAKER + STOP_LOSS_LIMIT
    • Now OCOs can be composed of the following order types:
      • LIMIT_MAKER + STOP_LOSS
      • LIMIT_MAKER + STOP_LOSS_LIMIT
      • TAKE_PROFIT + STOP_LOSS
      • TAKE_PROFIT + STOP_LOSS_LIMIT
      • TAKE_PROFIT_LIMIT + STOP_LOSS
      • TAKE_PROFIT_LIMIT + STOP_LOSS_LIMIT
    • This is supported by the following requests:
      • POST /api/v3/orderList/oco
      • POST /api/v3/orderList/otoco
      • orderList.place.oco
      • orderList.place.otoco
      • NewOrderList<E>
    • Error code -1167 will be obsolete after this update and will be removed from the documentation in a later update.

  • Timestamp parameters now reject values too far into the past or the future. To be specific, the parameter will be rejected if:

    • timestamp before 2017-01-01 (less than 1483228800000)
    • timestamp is more than 10 seconds after the current time (e.g., if current time is 1729745280000 then it is an error to use 1729745291000 or greater)

  • If startTime and/or endTime values are outside of range, the values will be adjusted to fit the correct range.

  • The field for quote order quantity (origQuoteOrderQty) has been added to responses that previously did not have it. Note that for order placement endpoints the field will only appear for requests with newOrderRespType set to RESULT or FULL.

    • Please refer to the table for requests with origQuoteOrderQty:
    ServiceRequest
    RESTPOST /api/v3/order
    POST /api/v3/sor/order
    POST /api/v3/order/oco
    POST /api/v3/orderList/oco

    orderList.cancel
    order.cancelReplace

SBE

  • A new schema 2:1 spot_2_1.xml has been released. The current schema 2:0 spot_2_0.xml will thus be deprecated, and retired from the API in 6 months as per our schema deprecation policy.
  • Schema 2:1 is a backward compatible update of schema 2:0. You will always receive payloads in 2:1 format when you request either schema 2:0 or 2:1.
  • Changes in SBE schema 2:1:
    • New field origQuoteOrderQty in order placement/cancellation responses (Note: Decoders generated using the 2:0 schema will skip this field.):

    • Added a new field userDataStream indicating if the user data stream subscription is active.
  • Fixed a bug where you wouldn't receive a new listenKey using userDataStream.start after session.logon

User Data Stream

  • WebSocket API only: New event eventStreamTerminated is emitted when you either logout from your WebSocket session or you have unsubscribed from the user data stream.
  • New event externalLockUpdate is sent when your spot wallet balance is locked/unlocked by an external system.

FIX API

  • The schema has been updated with a new Administrative message News <B>, which can be used for all FIX services. Receiving this message indicates that your connection is about to be closed.
  • Note: This message will be available in the live exchange at a later date.

General changes:

  • Symbol permission information in Exchange Information responses has moved from field permissions to field permissionSets.
  • Field permissions will be empty and will be removed in a future release.
  • Previously, "permissions":["SPOT","MARGIN"] meant that you could place an order on the symbol if your account had SPOT or MARGIN permissions. The equivalent is "permissionSets":[["SPOT","MARGIN"]]. (Note the extra set of square brackets.) Each array of permissions inside the permissionSets array is called a "permission set".
  • Symbol permissions can now be more complex. "permissionSets":[["SPOT","MARGIN"],["TRD_GRP_004","TRD_GRP_005"]] means that you may place an order on the symbol if your account has SPOT or MARGIN permissions and TRD_GRP_004 or TRD_GRP_005 permissions. There may be an arbitrary number of permission sets in a symbol's permissionSets.
  • The weight of the following requests has increased from 10 to 25:
    • GET /api/v3/trades
    • GET /api/v3/historicalTrades
    • trades.recent
    • trades.historical

REST API

  • The POST /api/v3/order/oco endpoint is now deprecated on the REST API. You should use the new POST /api/v3/orderList/oco endpoint instead. Note that this new endpoint uses different parameters.
  • POST /api/v3/order/oco has been removed from the Rest API documentation for SPOT Testnet.
  • otoAllowed will now appear on GET /api/v3/exchangeInfo, that indicates if One-Triggers-the-Other (OTO) orders are supported on that symbol.

WebSocket API

  • The orderList.place request is now deprecated on the WebSocket API. You should now use the new orderList.place.oco request instead. Note that this new request uses different parameters.
  • orderList.place has been removed from the WebSocket API documentation for SPOT Testnet.
  • otoAllowed will now appear on exchangeInfo, that indicates if One-Triggers-the-Other (OTO) orders are supported on that symbol.

SBE

  • A new schema 2:0 spot_2_0.xml has been released for SPOT Testnet. The current schema, 1:0 spot_1_0.xml, will thus be deprecated and retired from the Testnet APIs in 6 months as per our schema deprecation policy.
  • When using schema 1:0 on REST API or WebSocket API, group "permissions" in message "ExchangeInfoResponse" will always be empty. Upgrade to schema 2:0 to find permission information in group "permissionSets". See General changes above for more details.
  • Responses for deprecated OCO requests are supported by both schema 1:0 and 2:0
